Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, in particular to gastroenterology. The substance of the invention lies in the fact that in patients with gastric ulcer with the localization of ulcers in the antrum of the stomach associated with Helicobacter pylori (H. pylori) and Epstein-Barr virus (EBV), not only H. pylori contamination of the gastric mucosa is assessed, but also using the polymerase chain reaction method, the number of EBV copies is detected per 10 5  cells of the infiltrate. When detecting the number of EBV copies from 10001 or more per 10 5  cells of the infiltrate, the severity of the course of the disease is assessed as severe. If the number of EBV copies is found from 1001 to 10,000 per 10 5  cells of the infiltrate, the severity of the course of the disease is assessed as average. If the number of EBV copies is found from 101 to 1000 per 10 5  cells of the infiltrate, the severity of the course of the disease is assessed as mild. If the number of EBV copies is detected up to 100 per 10 5  cells of the infiltrate, the treatment of the Epstein-Barr virus is carried out as if the severity of the disease was mild. Subject to the presentation of complaints and the detection of gastric ulcer or a picture of pronounced antral gastritis during fibrogastroduodenoscopy, in other cases, treatment of the Epstein-Barr virus is not required. 
     EFFECT: invention provides an increase in the efficiency of diagnostics of the course of gastric ulcer with ulcer localization in the antrum of the stomach associated with H. pylori and EBV, timely predicting the course of the disease and optimizing the treatment of patients, reducing the number of exacerbations.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, to vascular surgery, in particular to phlebology. Prior to cyanoacrylate obliteration, a radiofrequency catheter with a heating element is inserted into the lumen of the vein and set 2.0 cm below the saphenofemoral/saphenopliteal fistula. Then, on a vein with a length of 7-10 cm, radiofrequency obliteration is performed. Then the radiofrequency catheter with the heating element is removed. A catheter filled with glue is inserted into the lumen of the vein to the previously obliterated area and cyanoacrylate obliteration is performed. 
     EFFECT: method allows excluding the ingress of glue into the deep venous bed, reducing the risk of embolization of the pulmonary artery and its branches with glue fragments, the development of glue-induced deep vein thrombosis due to thermal filling of the initial section of the vein, reducing the amount of anesthetic used, achieving the absence of the formation of a long stump of the vein trunk after surgery due to an indent of 2 cm from the saphenofemoral/saphenopliteal fistulas, which reduces the risk of recurrence of the disease.
